I summarize research articles of interest to my readers, for example at https://www.ptsdexams.net/disability-exams-research.html .
I noticed today that a link contained unusual characters (for a doi link), that I learned is URL encoding to a valid ASCII format, specifically %2F instead of a forward slash (/).
I also noticed that if I use the URL without the URL encoding, it still works, although Chrome converted the URL, as did Microsoft Edge.
Firefox and Opera did not convert the URL, although either URL worked on those browsers.
It seems to my less-knowledgeable mind that it does not make a difference which URL I use on my website, but I want to ask the experts to make sure. Thus, my question: Should I use URL encoding for doi links, or does it matter?
(1) I did search for other posts about this topic. The two most similar posts were How to remove %2F from the URL? and How to get rid of crawling errors due to the URL Encoded Slashes (%2F) problem in Apache
(2) Browser versions I used:
Chrome 84.0.4147.125 (Official Build) (64-bit)
Microsoft Edge 84.0.522.59 (Official build) (64-bit)
Firefox 79.0 (64-bit)
